Article Abstract

Intrahepatic cholangiocarcinoma (ICC) is a primary liver cancer with insidious onset, rapid progression, and poor prognosis. The lymphatic system is the main route of ICC distant metastasis, with lungs, adrenal glands, and brain as the most common extrahepatic sites. However, extrahepatic metastases of ICC have rarely been reported in patients with rectal symptoms as initial symptoms, and the diagnosis relies on the specific immunohistochemical features of intestinal lesion biopsy. Herein, this study presents an incidental case of ICC with rectal metastasis to investigate its characteristics based on its diagnosis, metastasis, and treatment.

Background: The accuracy of CA19-9 detection results is very important for the early detection and treatment of pancreatic cancer, cholangiocarcinoma and other malignant tumors. At present, endogenous substances such as heterophilic antibodies will cause interference in the commonly used detection method is electrochemilumines-cence immunoassay, resulting in inaccurate results and affecting clinical diagnosis and treatment.

Methods: This paper reports a patient with an abnormal increase in serum CA19-9 level to explore how to accurately identify non-specific interference and anti-interference countermeasures.

Background: Right-sided hepatectomy (RH) is the standard surgical approach for perihilar cholangiocarcinoma (PHC) due to anatomical considerations but is associated with a high risk of post-hepatectomy liver failure (PHLF). Left-sided hepatectomy (LH) and central hepatectomy (CH) have been proposed as alternative strategies to preserve liver function, but the feasibility and outcomes of CH have not been sufficiently investigated. CH allows for greater preservation of liver parenchyma, potentially reducing the risk of PHLF.

Background: The role of liver transplantation as a treatment option for de novo resectable peri-hilar cholangiocarcinoma (pCCA) is controversial. This study investigated the outcomes following resection of early-stage pCCA in the UK.

Methods: Patients undergoing resection for pCCA between 2014 and 2022 across 22 UK centres were included.

Cholangiocarcinoma (CCA) is a fatal bile duct malignancy. CCA is intrinsically resistant to standard chemotherapy, responds poorly to it, and has a poor prognosis. Effective treatments for cholangiocarcinoma remain elusive, and a breakthrough in CCA treatment is still awaited.
